Min*_*rid 2 android firebase firebase-cloud-messaging
根据Firebase 文档:
当 App 在前台时:
onMessageReceived 被调用,我可以显示推送通知并对数据进行任何处理(在这种情况下我没问题)。
当应用程序在后台时:
通知系统托盘将显示通知,一旦用户点击通知,启动器活动将被调用,通知数据将在捆绑包中传递给启动器活动。
我的问题是,当应用程序在后台时,通知系统没有显示通知。
我没有使用 Firebase 控制台,因为我无法向通知负载添加数据。所以我使用了 RESTful 客户端 API,但它仍然是同样的问题。

当应用程序在前台时此技术有效,但在后台时它不起作用
安卓代码:
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
sendNotification(remoteMessage.getData().get("title"),remoteMessage.getData().get("body"));
}
private void sendNotification(String messageTitle,String messageBody) {
Intent intent = new Intent(this, SplashActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this,0 /* request code */, intent,PendingIntent.FLAG_UPDATE_CURRENT);
long[] pattern = {500,500,500,500,500};
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.roshetta_logo_home)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setAutoCancel(true)
.setVibrate(pattern)
.setLights(Color.BLUE,1,1)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());

每次我们在华为手机上出现问题时,都是因为该应用程序不是“受保护的应用程序”。
